# FAQ: What's Radio and how does it work?
---
Roon works to match every song in your library, so we know exactly when each song was released, who played on the song, what label it came out on, what genre it is, and lots, lots more.
Our Radio feature uses this metadata to create a personalized station for you, playing similar songs from your collection.
Radio starts when you click any music in your library and choose the Radio button:

----------
By default, Radio will also start whenever there aren't any more tracks in your Queue:

You can turn this feature off by clicking No in the Queue. Access the Queue by clicking the name of the currently playing track along the bottom of Roon, or by pressing CTRL/CMND + E.
----------
Once Radio is active, you can thumbs up tracks to add them to your Queue, or thumbs down them to skip the selection.

### Radio Ban Tag
Starting in Roon 1.5 (Build 354), any track with the file tag ROONRADIOBAN set to values 1 or true or yes will no longer be selected by Radio.
